If you use Mac, try this link for updates to “drivers” for your printers. Clicking the “download” button on that apple site takes you to the respective company page for downloading the driver you need. It seemed to me easier to direct you / me to Apple rather than my maintaining an updated link exchange to the companies.

Have downloaded the Photoshop SDK for Mac. Now pluging (:) through the examples … looks like XCode, but also like converted “to” xcode … Xcode was never my favorite dev environment. At least the Adobe Forums seem to be monitored regularly. [ part of my reaching toward the perfect print ] The command line test routines have been stubbed out. Pretty easy since I’m taking from old/dead/abandoned projects. Much like photographing in ghost towns. Code has such a low dynamic range … Those command lines will eventually be used by the plugin, or from cmd by a knowledgeable user.
